When your OS goes crazy - Screenshots

Not so much a screw-up as utilization of some common failures in this thread;
I made a program to show memory "graphically" by copying it to the command buffer.
You can move it forward 1 byte with A or 1024 bytes (1 kb.) with B, and show a little help info + the current location with C.
Here is a demo pic:

NEVER try this on real hardware!!!! This could potentially have problems (corrupting memory) if you are not careful (accidentally writing video memory to the hard drive)

Phewph! I did test it on real hardware, however it was an Acer laptop which refused to boot Windows anyways.
Thank you for the warning.

Some rather interesting results originating from (I assume) a faultly paging implementation, or a bug in my memcpy function :

Very interesting, gallery-worthy images! Good luck, I hope you find the source of the bug.

Fixed the bug, it was my physical page allocator that was freeing the wrong pages, thus allowing allocated memory to be corrupted
It's sooo satisfying to find the source of a bug tho ^^

I don't know where else to put this, but the title of the section is fitting.

I can get my OS to compile properly, but I can't boot it in virtualbox and qemu just decided that it doesn't want to work on my system. And I hate bochs.

I don't have screenshots, but I can tell you right now that i tested this.

Ok, so it's not entirely my system, i was going to modify it to my needs. https://github.com/SamyPesse/How-to-Mak ... ing-System

It compiles fine but I can't boot the images.

p.s. move this somewhere if necessary, i don't know where it should go.

EDIT: i might want to use the right system to compile it... time to download vagrant. Sorry for hijacking the thread

After implementing multitasking and adding a small clock in the right top corner, all sorts of weird stuff started happening, like this.

That's jazzy as heck. More, please! I want a wallpaper like that.

Trying to execute v8086 code moved 0 to endless in physical memory and generated this weird thing:

New 8x8 fonts don't completely work.

Real hardware is different from QEMU, I guess..

Testing a rectangle drawing function I wrote in assembly with different resolutions, not what I was expecting but it's a modern abstractionist masterpiece and I want to tour with it to galleries worldwide, schmoozing & sipping fine wines that taste like anti-freeze if I can get the expenses paid for
